 EMI2.1 
 145 bis 165 , vorzugsweise etwa 1580 ist. Nahe der   Schneiden --5-- sind   in den Flanken-3im Querschnitt etwa kreisförmige   Spanformnuten--4--vorgesehen.   Diese dienen zur Formung bei der kleinen Vorschüben gebildeten Späne. Bei grösseren Vorschüben erfolgt die Spanformung durch eine   Spanformplatte--11--.   



   Wie in den Fig. 4 bis 6 gezeigt ist, liegt die festgeklemmte Schneidplatte-l-auf einer am Halterschaft--8--mittels eines Rohrstiftes --9-- befestigten Auflageplatte --10-- auf. Auf der 
 EMI2.2 
 sich um eine Innensechskantschraube handelt) an die   Schneidplatte-l-angepresst.   Zwischen dem Kopf. --13'-- der Spannschraube --13-- und der   Klemmpratze --12-- befindet   sich eine Federscheibe-14--. Um die Klemmung der   Spanformplatte --11-- und   der Schneidplatte --1-- zu verstärken, ist die Schraubenachse--a bis   c--gegenüber   der Normalen--a bis   b--auf   die Auflagefläche --12'-- der Klemmpratze --12-- merklich, vorzugsweise um einen Winkel 6 von etwa 2 , gegen die der wirksamen   Schneidkante --5-- abgewandten   Seite hin geneigt.

   Hiebei ist die auflagefläche --12'-- der Klemmpratze --12-- zu der   Auflagefläche-8'--des   Halterschaftes --8-- parallel. Weiters ist noch zu erwähnen, dass die   Auflageplatte--10--zwei   schräge Flanken   - -10'-- aufweist,   die an der Schneidplatte-l-anliegen. Infolgedessen kann die am Halterschaft   - 8--   befestigte Schneidplatte--l--durch die auf sie während des Kopierdrehens wirkenden Kräfte nicht verschoben werden.

    Clamp steel holder
 EMI1.1
 

 <Desc / Clms Page number 2>

 
 EMI2.1
 145 to 165, preferably about 1580. Near the cutting edges --5 - there are chip-forming grooves - 4 - which are approximately circular in cross section in the flanks - 3. These are used to shape the chips formed during the small feed rates. In the case of larger feed rates, the chip is formed by a chipboard - 11--



   As shown in FIGS. 4 to 6, the clamped cutting insert-l-rests on a support plate -10-fastened to the holder shaft -8 by means of a tubular pin -9. On the
 EMI2.2
 is a hexagon socket screw) pressed onto the insert-l-. Between the head. --13 '- the clamping screw --13-- and the clamping claw --12-- there is a spring washer -14--. In order to strengthen the clamping of the chipboard --11-- and the cutting insert --1--, the screw axis - a to c - opposite the normal - a to b - is on the support surface --12 '- the clamping claw --12-- inclined noticeably, preferably at an angle 6 of about 2, towards the side facing away from the effective cutting edge --5--.

   The support surface --12 '- of the clamping claw --12-- is parallel to the support surface - 8' - of the holder shaft --8--. It should also be mentioned that the support plate - 10 - has two inclined flanks - -10 '- which rest against the cutting plate-1. As a result, the cutting tip attached to the holder shank - 8 - cannot be displaced by the forces acting on it during the copy rotation.

PATENTANSPRUCH : Klemmstahlhalter, insbesondere zum Kopierdrehen, bei dem eine Schneidplatte, die eine im Querschnitt etwa kreisbogenförmige Spanformnut aufweist, mittels einer Klemmpratze und einer durch diese hindurchgehenden Spannschraube od. dgl. z. B. an einem Halterschaft festgeklemmt ist, wobei sich zwischen Klemmpratze und Schneidplatte eine eine schräge, zur Ablenkung der Späne dienende Fläche EMI2.3 dassQuerschnitt etwa kreisbogenförmigen Spanformnut (4) und der schrägen Fläche (11') der Spanformplatte (11) ein Abstand vorgesehen ist, so dass Schlichtspäne von der Spanformnut, Schruppspäne hingegen von der schrägen Fläche der Spanformplatte geformt werden. PATENT CLAIM: Clamping steel holder, in particular for copy turning, in which a cutting insert, which has a chip-forming groove approximately in the form of a circular arc in cross-section, by means of a clamping claw and a clamping screw passing through this od. B. is clamped to a holder shaft, with an inclined surface serving to deflect the chips between the clamping claw and the cutting plate EMI2.3 that cross-section approximately circular chip-forming groove (4) and the inclined surface (11 ') of the chip-forming board (11) a distance is provided so that finishing chips are formed from the chip-forming groove, while roughing chips are formed from the inclined surface of the chip-forming board.
